IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent and making part of tix-c came To all whom 'it mayconccru Be it known that we, EDWARD S.(JAvNA1-1 andl DAVID ,YEAGLEL of Bourbon, in the county of Marshall, and State of Indiana, have invented certain new and useful Improvementsin Pumps; and wedohercby declare the following to be a t'nll,"clear, and exact description ofthe same, reference being had to the accompanying dravings,making a part of this specification, in whichi t Figure l represents a perspective View of the exterior ofthe pump, and

Figure 2 represents a vertical section through the same. i

Our invention relates to an-arrangement of circularl or disk-valves, that have butl a slight rising and falling motion,which, not requiring packing, are very 4durable and reliable; these valves-being so' arranged in connection with pul'np-cylinder and valve or pumprod, as to raise the water by lifting, and not by suction, and, asabove stated, by avery slight motion of' the valves from their seats.

To enable others skilled in the art to make and use our invention, we will proceed to describe the saine in reference to the drawings.

A represents'a cast-iron cylinder, which is sup-l ported o'n a bottom or base-plate, B, that isin turn supported in the well, and near the bottom ofthe well, on legs or stands c.

Through the bottom or `base B there is awater-way, I), which is covered on the inside of the cylinder by a flat circular leilatc-valve, af, which has its seat at b, and is controlled in the ext-ent of its upward movef ment by the guides c c. ',lihe valve a rises and falls in a horizontal plane, and is neither hinged nor packed, and there is, consequently, not-hing to wear out.

Through thc top E of the cylinder there is a waterway, F, commanded by a valve, d, formed and operxated like that, a, above described, its seat being at e,

.and its guides shown at j'.

The valve or punip-rod (lr passes through the upper valve (l, andhas upon its lower end a ringvhead, H,

through which there are water-ways, q g, of any suit able number, vand ou top of which there is an annular iange,1', that'forms a scat for the circular valve h, which has also a liorizontally risi11g-a11d-fa-lling motion, equal to the distance from the flange-scat 'i to a stop or collar, m, on the pump-rod G, thc stem ofthe pumprod being the guide to the valve h. and the valve h, are without hinges or packing, and the extent of their motions so slight that there isno slamming or wearing by their action.

On top ofthe cylinder is secured, bythe screw-rods I I, or otherwiscfa conical picco, J, which iinally unites with the water-pipe or stock li, through which the water is raised, the pump-rod (rl passing through said tube, pipe,'or stock, and extending down to near the bottom of the cylinder A. The valves and the water-ways cr passages are in a direct line 'ii-om thc bottom of the cylinder to ucar the top et the pipo, tube, or stock, from which point itmay deflect iioni the direct lille. v

AHaving thus fully described our invention,

What we claim therein as new, and desire to sccure by Letters latcnt, is-

' ln combination with the cylinder A, and pipe, tubc, stock, or water-passage extending upward thorcfi'om, the openings l) F in 4thc heads oi' thc cylinder, and the openings q in the plunger, when said opcningsarc controlled by the circular valves (t (t h, onorating in the manner and ior the purpose dcscribi-id and rcprcsented.
